| 摘 要： | 传感器节点能量是影响无线传感器网络的生存周期的关键因素,基本的GPSR协议所使用的贪婪算法忽略了角度因素对下一跳选择的影响,在转发失败遇到空洞问题时只能进行周边边界转发算法,以损耗节点能量为代价。为了节约节点能量,延长网络生存周期,从改进GPSR协议出发,综合考虑距离和角度这两个因素解决路由过程中的空洞问题。仿真实验表明,改进后的协议是网络节点消耗大大减少,网络生存时间为300 s,长于基本GPSR协议下的200 s。该协议缩短了路径长度,节约节点能量,减少能量的消耗,延长了网络生存时间。

A GPSR Routing Protocol for Wireless Sensor Networks Based on Distance and Angle |
| |
| Abstract: | The energy of sensor node is one of the key factors affecting the lifetime of wireless sensor network. Greedy algorithm in GPSR protocol ignored the influence of angle in the next hop selection. When there is a forwarding failure, only a peripheral edge forwarding algorithm could be used to solve the problem, with the loss of node energy as the price. In order to save energy of the sensor nodes and prolong the network life cycle, the algorithm, the problem of void in the route was solved from the distance and the angle in this study. Simulation results showed that the improved protocol greatly reduced node energy, and the network lifetime was 300 s, which was longer than before. The protocol can shorten the length of path, save node energy, reduce the consumption of energy and prolong the network lifetime. |
